Title: Added handling for textures with premultiplied alpha (needed for textures

Added handling for textures with premultiplied alpha (needed for textures converted from CGImages).

There may be a slight performance benefit to be gained by changing some values for the premultiplied flag from NO to YES (for instance, for the alpha-less RGB format). I stuck with NO in these cases simply because I wanted my changes to be conservative, and I don't have test cases for each format.
